UNITED STATES PATENT OFFICE.

OIJIVIER F. DUBOIS, OF TURTLE LAKE, IVISGONSIN, ASSIGNOR OF ONE-HALF TOJOHN H. BUNKER, OF SAME PLACE.

HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 437,146, datedSeptember 23, 1890.

Application filed December 23, 1889. Serial No. 334,663. (No model.)

To all whom it may concern.-

Be it known that I, QLIVIER F. DUBOIS, a citizen of the United States,and a resident of Turtle Lake, in the county of Barron and State oflVisconsimhave invented certain new anduseful Improvements inHay-Presses andI do declare the following to be a full, clear, and exactdescription of the invent-ion, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the'accompanyin g drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure 1 is a side elevation of my improved hay-press. thereof with thebaling chamber in use. Fig. 3 is a rear end view thereof; and Fig. 4 isa detailed, partly broken away, view of a modification of the mechanismfor actuating the follower.

This invention relates to certain improvements in presses designed moreespecially for baling hay; and it consists of the novel combination andconstruction of parts, as will fully appear from the followingdescription and accompanying illustrations.

In accordance with my invention, I employ a suitablehorizontally-disposed receptacle or chamber A, within which hay isplaced for compression and formation into a bale. The baling-chamberproper A of the receptacle A has in opposite sides longitudinal slots ata, through which to pass the binding wire or rope. In the top of thischamber A is an upwardly-opening door B, hinged at one end, as at b, toa frame of the receptacle A, the said door having secured to its upperside at the outer or free end a cross-bar b, projecting beyond the sideedges of said door and provided with hooks c, engaging eyes or staples c011 the end uprights cl at that end of the receptacle A. At a suitabledistance from the door B, I may provide the receptacle A with aseconddoor (not shown) to permit feeding the hay thereinto by two or morepersons at different points and at the same time. In the outer end ofthe baling-chamber A is placed a removable end piece or board f, fittingthe same snugly, its bottom edge resting in a shallow groove or gain ginthe bottom Fig. 2 is a longitudinal section or floor of said chamber,while its upper or top edge is received in a shallow groove or gain g inthe under side of the door B, which, together with the groove or gain g,prevents displacing the gate by the pressure of the contents.

0 is a drum which stands vertical and has an axial bearing in the bottomand top of the receptacle A.

D is the follower, which fits closely the receptacle or chamber A toeffect the compression of the hay or contents of the latter, and whichhas its exteriorstem orbarD connected, preferably by a rope or chain Dwith the Windlass or drum 0, in order to actuate said follower.

E is a guide-bar secured by a pendant E to the receptacle A, and havinga ledge or rabbet E extending in the direction of its length and havingthe follower-bar D resting and guided thereon. This guide-bar, togetherwith an overhanging bracket E fastened to the guide-bar at its inner endand receiving in a groove h in its under side the upper longitudinaledge of the follower-bar, serves to keep said bar in a right line.

G is a sweep or pole connected to the upper end of the Windlass 0. Bymeans of this sweep motion is imparted to the Windlass to operate thefollower, said pole or sweep in practice being adapted to permithitching a horse thereto or applying to it other power.

It will be seen that the horizontal receptacle, with its extensionguide-bar, is within the diameter of the circle described by themovement of the sweep, thus providing a compact arrangement of the partsand economizing space.

In the modification, as disclosed in Fig. 4, the follower-bar D isprovided with teeth 0 on one edge, with which is caused to engage apinion O on a vertical shaft suitably journaled in the press-box frame,said followerbar resting upon a suitably-supported roller B and held inengagement with the pinion C by a roll F, also suitably supported inposition.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

In a baling-press, the combination of the receptacle or chamber providedwith a removable end, the follower, the Windlass or drum, a rope orchain, the follower bar or stem, and the guide-bar having a ledge orrabbet and a bracket overhangin said ledge or rabbet and having a groovein its under side directly above said ledge or rahbet, said followerbeing" guided in a right line by said ledge or rabbet and bracket andsaid follower-bar eon- 1o nected by said rope or chain to said Windlassor drum, substantially as specified.

In testimony whereof I ai'lix my signature in presence of two Witnesses.
